How to eliminateMulti-function hydraulic pressOil pump trapped oil phenomenon, the method is very simple, just in the oil pump sleeve or pump shell on the opening of the unloading groove. However, it should be noted that the size of the unloading groove should be able to ensure that the phenomenon of trapped oil is well eliminated, and at the same time it will not cause excessive leakage, or the pressure oil cavity and the suction cavity are connected.

When the hydraulic gear pump is working, the pressure on the side surface of the oil pump gear is inconsistent. Generally, the pressure near the oil suction chamber is smaller than that near the oil discharge chamber. This is also caused by the gap between the tooth top and the pump casing. Therefore, measures must be taken to balance the radial force on the gear.
